Autonomous Agent

An autonomous agent is a software system that works toward a goal over multiple steps without a human directing each one. Rather than answering a single prompt and stopping, it perceives the state of its environment, decides what to do next, takes an action, observes the result, and repeats until the objective is met or a stopping condition is hit. In modern systems the decision-making is usually driven by a large language model that plans and selects tools, while the surrounding code supplies memory, tool access, and the loop that keeps it running.

Autonomy is a spectrum rather than a binary. A highly autonomous agent might run a long task end to end; a more constrained one proposes each consequential action and waits for a person to approve it. The constrained pattern — often called human-in-the-loop — is common in business software, where the cost of a wrong action (a sent email, a charged card, a deleted record) is high. There, the agent does the reasoning and drafting autonomously but defers the final commit to a human.

In business software, an autonomous agent is usually scoped to one role, given access to specific tools and data, and started by a schedule, an event or a person's request. Practical deployments add guardrails — permission boundaries, per-tenant data isolation, audit logs, and approval gates — so that autonomy stays bounded and reviewable instead of open-ended.
